Title: Distribution type fuel injection pump
Inventor: KATO NOBUO
IPC: F02M41/14
Filed: 1992-04-30
Abstract: PURPOSE:To improve durability by reducing vibration applied to a rotation sensor, and control injection quantity and injection timing correctly. CONSTITUTION:In an injection pump 20, a rotor 33 which rotates integrally with a drive shaft 38 is provided with a plunger 35 to slide diametrically, and a cam ring 37 to actuate the plunger 35 is provided at an outer circumference of the rotor 33. A rotation angle position is detected by a pulser 56 fixed to a large diameter part 33a of the rotor 33 and a rotation sensor 55 fixed to the cam ring 37. A slide pin 66 of a timer part 65 disposed at an outer circumferential part of the cam ring 37 slides the cam ring 37 along the circumference to regulate fuel injection timing. The rotation sensor 55 is disposed almost at the same position in the circumference of the cam ring 37 to the slide pin 66. A distance between the rotation sensor 55 and the slide pin 66 is thus set short, thereby vibration of the rotation sensor is reduced.

Title: Method and instrument for measuring inclination
Inventor: TANABE MASARU
IPC: G01B11/26
Filed: 1992-04-30
Abstract: PURPOSE:To quickly and accurately measure the inclination of a slope against a specific plane in a nondestructive way. CONSTITUTION:Parallel measuring light rays are condensed on a slope 220a to be measured by means of a condensing means 120 having a specific optical characteristic. At the time of condensing the light rays, the passing area of the light rays L0 in a reference plane 300 is set to a measurement light area A and the passing area of reflected light rays L1 of the light rays L0 from the slope 220a in the plane 300 is set to a reflected light area B. The area of the overlapping area C of the areas A and B in the plane 300 or the physical quantity proportional to the areal ratio between the areas A and B dependents upon the inclination theta of the slope 220a. Therefore, when the inclination of the slope 220a is found by finding the physical quantity by utilizing such relation, the inclination theta can be quickly and accurately measured in a nondestructive way.

Title: Revolving magnetic field driving circuit
Inventor: ISHIDA KAZUHIRO
IPC: G11C19/08
Filed: 1979-09-03
Abstract: PURPOSE: To reduce electric power consumption when a circuit is not in operation and to facilitate control over input pulses, by applying a transistor in an ON state as a bias with a voltage developed across the secondary winding of a four-winding pulse transformer.  
     CONSTITUTION: When pulse signal (a) from terminal 24 is applied to primary winding 23a of four-winding pulse transformer 23, a voltage developed across secondary winding 23c is applied between the base and emitter of transistor TR5, which turns on and a voltage across secondary winding 23d is applied between the base and emitter of TR10, which is reversely biased to discharge its storage charge, turning off TR10. Therefore, TRs 5 and 10 never turn on simultaneously. Next, applying pulse signal (b) to terminal 25 never causes TRs 5 and 10 to turn on sumultaneously.

IPC: H03K19/173
Filed: 1991-04-18
Abstract: PURPOSE:To change the function of an input buffer without reforming a semiconductor integrated circuit. CONSTITUTION:If the input of a low level is applied to the input terminal 1 of an inversion type input buffer 2 when the output terminal 6 of a ROM 5 is kept at a low level, the output terminal of a 2-input NOR circuit 3 is set at a low level and an N type field effect transistor TR 4 is interrupted. Therefore the buffer 2 functions as a conventional type, but the output terminal of the circuit 3 is set at a high level when the input of a high level is applied to the terminal 1 of the buffer 2. Then since the TR 4 is conducted, the threshold level of the buffer 2 is reduced. Thus it is recognized that tow threshold leves are present thereon with the input of the buffer 2.
